question on 2383 twim motors

Not the same, yours have a single screw on the bottom of each truck that holds the motor on, remove that and the motor will come off, clean and refill with grease oil all bushings, brushplate wick.

thanks   tstark

The 2383 has 2028-100 motors in them. This motor is commonly used with the GP-7/9 road switchers. This motor is very different from the motors in the 2343 as the field, brushplate, and armature assemblies are very different in shape and contours.

If you look up the parts diagram for the 2028 you will find the motor and truck assemblies there for the 2383.
